Molecular biogeography of clonal lineages in a high‐Arctic apomictic Daphnia complex
Abstract An electrophoretic survey of 81 populations of arctic Daphnia pulex from around the Svalbard archipelago revealed the presence of 49 unique allozyme clones ( N = 3357). Two closely related clones accounted for 66% of the total sample, and were widespread across the archipelago. Restriction...
